Subject: [PATCH v3 1/2] mmc: meson: adjust and re-use constant IRQ_EN_MASK
Date: Thu, 25 Aug 2022 21:53:42 +0200 [thread overview]
Message-ID: <8056622f-2adf-4763-7423-9ccdf4ca78e1@gmail.com> (raw)
In-Reply-To: <72459a46-fd20-60d8-a7e7-076d8f321816@gmail.com>
Constant IRQ_EN_MASK has no user currently. In preparation of adding
SDIO interrupt support, revive it and adjust it to our needs.
